Abstract

The present invention relates to the technical field of illumination, and discloses an organic electroluminescent device comprising a first electrode, an organic light-emitting layer and a second electrode stacked on a substrate. The second electrode includes a plurality of parallel electrode bodies arranged above the organic light-emitting layer, and a wire connection part provided on the substrate. The electrode bodies and the wire connection part are electrically connected through a short-circuit prevention component. The short-circuit prevention design structure is provided in the second electrode, and the impedance between the electrode bodies of the second electrode and the wire connection part of the second electrode is increased by the short-circuit prevention structure, so that the current passing through the second electrode is limited to protect the device function.

Description

technical field [0001] The invention relates to the technical field of lighting, in particular to an organic electroluminescence device and a preparation method thereof. Background technique [0002] Organic electroluminescent device (English full name Organic Light-Emitting Device, referred to as OLED) adopts organic electroluminescent material, is an active light-emitting device, has the advantages of low power consumption, wide color gamut, and thinner volume, and is expected to become the next generation of mainstream lighting and flat panel display technology. At present, organic electroluminescent technology has been widely used in small-sized panels such as smartphone displays. [0003] Organic electroluminescent devices are usually composed of stacked anode layers, light-emitting layers and cathode layers, and are often used as large-scale devices in the field of lighting. Due to the large area of ​​each film layer, during the preparation process, pollutants often ...
